[It's right as the final boss largest creature appears that he knows he can't do this anymore, that no matter how much energy he may have spent giving to the cause of restoring the trees, he- can't let Sorey fight something like that alone. And if he can't fight beside him...]
Sorey!
[He yells to get his attention -- rather than in a worrying tone, a suggestion in it, expecting he'll know right away. Let's do the thing.
Mikleo's physical form will disappear in a blue light and when Sorey calls his true name (Luzrov Rulay) a transformation occurs, water blasts shooting from the large bow their merged form wields together. It will take until the change back to normal Kiseki for them to split up again, left sleeping near each other... though of course anyone that may have witnessed it could say something once they wake up just as well.]
